The enlargement of the euro area: what lessons can be learned from EMU?

This paper investigates what lessons may be learned from EMU for the enlargement of the euro area. It examines the situation of present and prospective EU countries in respect of nominal and real convergence. It suggests that fulfilling the EMU criteria consistently over the next few years will require huge efforts by prospective EU countries, with important output and employment losses. The possibility that present EU countries would have to bear part of these costs cannot be ruled out, with the risk of provoking tensions within the EU, in particular as regards the ‘one-size-fits-all’ monetary policy decisions of the ECB.
